Unhappy with Vodacom's sloppy service delivery

I made a query on the 2nd April'15 regarding a Vodacom deduction made from my bank account for February. It's been over a month since I inquired about the deduction. The name of the agent I spoke to was Zandile and she referred me to Tshepiso Mogatle (team leader: TL).<br> I called to follow up again, but the line would say that unfortunately my call could not be taken due to unforeseen circumstances. But on the 4th of May I finally got through to Lwazi, who referred me to Nelson Sit**** (TL). He also promised to follow up because the logged call I waited for, had been lost. I spoke to Nelson again, Elizabeth, a lady from \Accounts"whose name I forgot to record"
